Oxc, Rolldown, Vitest, Vite: The Future of The JavaScript Toolchain
summary
Overview of concrete changes and performance: Oxc ships a Rust parser and toolchain that benchmarks Oxc parser 3× faster than SWC, and a linter and formatter that claim Oxc linter 50–100× faster than ESLint and formatter 3× faster than Biome. Weldon (Rollup Dawn) is a Rust bundler built on Oxc and becomes the default bundler in Vite 8, promising far faster builds and an experimental full-bundle dev mode to remove dev/prod build inconsistencies. JavaScript plugin APIs use raw transfer and lazy deserialization to keep DX without huge overhead.
